I don't enjoy shopping, so will be happy to see more social spaces where retail used to be, and continue to shop online. I think that trying to revive the High Street as we used to know it is like trying to turn back the tide. People like to shop when it suits them, which the internet allows. I would hate to go back to the days of spending every Saturday in Tesco, with 2 small children taken along as I don't drive, so Mr Dog had to come too. Not the best use of my day off at all, and every other family in the world seemed to be in there too, looking equally fed up. Sitting in front of the TV with a cup or glass, and doing a leisurely shop that someone will bring to the door is so much pleasanter, and I did it as soon as online shopping came on stream, meaning I could do things with the family on Saturdays.
I would like to see High Streets become places where people don't have to spend money (although I doubt that councils will subsidise them, so I don't hold out a lot of hope), and places where people of all ages can meet and mingle, with options other than drinking alcohol. Combating loneliness and cutting down on the need to drive everywhere should be priorities for councils, IMO. There could be community hubs where people could go for a chat, mending cafes to take broken items to be fixed, swap shops, classes, places for interest groups to meet and so on. More commercial ventures such as bowling allies and cinemas might find that people will put up with not having the huge choice offered by a multiplex in return for being able to walk there and stop off for a drink or food that is not necessarily in the sort of fast food place that is usually next to cinemas. Small independent shops could still sell Etsy-type items, maybe in little market-style outlets where vendors could share the working hours.
I rather wish that High Streets would hurry up and go, so that there is a difference between living in town A and town B - these days there is often nothing to choose between them, as they all have similar chains.
